Answer:
a) 5units
b) (4.5, 4)
Step-by-step explanation:
Let the coordinate of P and Q be P(3, 2) and Q(6, 6)
PQ can be gotten using the distance formula;
PQ =√(6-2)²+(6-3)²
PQ = √4²+3²
PQ =√16+9
PQ =√25
PQ = 5units
Midpoint M is expressed as;
M(X, Y) = {(x1+x2)/2, y1+y2/2}
X = x1+x2/2
X = 3+6/2
X= 9/2
X = 4.5
Similarly;
Y = y1+y2/2
Y = 2+6/2
Y = 8/2
Y = 4
Hence the midpoint of PQ is (4.5, 4)
Given that events A and B are independent with P(A)=0.31P(A)=0.31 and P(B)=0.7P(B)=0.7, determine the value of P(B|A)P(B∣A), rounding to the nearest thousandth, if necessary.

Answer:
.7
Step-by-step explanation:
I'm going to assume you meant to write all that stuff once
The conditional probability formula is as follows : (B|A)=(A∩B)/A
We're told that the two probabliites are independent of each other which means that A∩B= A*B
Which means we have
(.31*.7)/(.31)
This should simplify to .7
*note* a shortcut you can use when finding the conditional probability of two independent probabilities you can just take the first probability (or in this case B) and that'll be your final answer

Step-by-step explanation:
An object is moving at a speed of 2 centimeters every 7 seconds. Express this speed in meters per week. Round your answer to the nearest whole number.
Answer:
v = 12121 m per week.
Step-by-step explanation:
Given that,
The object is moving at a speed of 2 centimeters every 7 seconds.
We need to find the speed in m per week.
2 cm = 0.02 m
1 week = 604800 s
7 s = [tex]1.65\times 10^{-6}\ week[/tex]
Speed = distance/time
So,
[tex]v=\dfrac{0.02\ m}{1.65\times 10^{-6}\ week}\\\\v=12121.21\ m/week \\\\or\\\\v=12121\ m/week[/tex]
So, the speed of the object is 12121 m per week.
Answer:
1728 meters per week, the answer of 1212 was wrong on my test.
Find the volume of the cylinder. Round to the nearest tenth
5 ft
2 ft
Given:
Radius of the cylinder = 2 ft
Height of the cylinder = 5 ft
To find:
The volume of the cylinder.
Solution:
Volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]\pi = 3.14,r=2,h=5[/tex] in the above formula we get the volume of the given cylinder is:
[tex]V=(3.14)(2)^2(5)[/tex]
[tex]V=(3.14)(4)(5)[/tex]
[tex]V=62.8[/tex]
Therefore, the volume of the given cylinder is 62.8 ft².

What is the Area of the compound shape below? *
Answer:
22m²
Step-by-step explanation:
2 wide, 9 height is 18 for the rectangle figure. We see that the rectangle figure has a width of 2 while the entire width is 4. So 4-2 means the width of the right triangle that's split off is 2.
We see the rectangle height is 5, and total figure is 9, so 9-5 = height of 4 for the triangle.
4x2 x 1/2(since its a triangle) = 4
4+18 = 22

What is the solutions set of y=x^2+2x+7and y=x+7
Answer:
when x=0 ,y=7
when x=-1, y=6
Step-by-step explanation:
Taking [tex]y=x^{2} +2x+7, y=x+7[/tex] as equation 1 and 2 respectively
Inserting equation 2 in 1,
[tex]x+7=x^{2} +2x+7\\[/tex]
getting rid of 7 since its in both the sides with the same + signs,

Answer:
What is the angle of elevation θ that is required for a hit ball to just clear the center field fence when it is hit 2 ft above the ground? Show all of your work and round your answer to the nearest hundredth of a degree.
Distance from Home plate to the center field fence: 425 ft
Height of the center field fence: 8 ft
____________________________
ANSWER:
The fence height = 8ft
The fence height takes 2 ft from the ground and doesn't count towards the angle.
Therefore subtract the difference = 8-2 = 6ft
The fence height from the 2ft to the fence top = 6ft
Angle of elevation (θ):
Tan(θ) = opposite/adjacent
Adjacent = Distance from Home plate to the center field fence = 425 ft
Opposite = 6ft
Tan(θ) = 6/425Tan(θ) = 0.0141θ = arctan(0.0141)arctan = inverse of tangent = tan-¹θ = 0.8078°Angle of elevation (θ) = 0.81°make a sentence with antonyms of

Answer:
Step-by-step explanation:
First, convert the equation into slope-intercept form: y > -3x + 5
Second, place a point on (0,5). You can do this by starting at the origin and counting up by 5. This is your y-intercept.
Third, start from your y-intercept and move down 3 and right 1. Draw a point. Keep doing this until you hit the end of the graph.
Fourth, start from your y-intercept and move up 3 and left 1. Draw a point. Keep doing this until you hit the end of the graph.
Then, connect your dots by making a dashed line.
Finally, Shade above the line.
Cos? Tan? Sin? What is angle V?
Answer:
60degrees
Step-by-step explanation:
SInce our reference angle is <V;
Opposite = WU = 7√3
Hypotenuse= WV = 14
Using the SOH CAH TOA identity
son m<V = opposite/hypotenuse
sin m<V = 7√3/14
sin m<V = √3/2
m<V = arcsin(√3/2)
m<V = 60degrees
Hence the measure of angle V is 60degrees

Solve: 2y - 4 = 14
Please answer I put the points up please answer quik
Answer:hope it helps
Step-by-step explanation:
Simplifying
2y + -4 = 14
Reorder the terms:
-4 + 2y = 14
Solving
-4 + 2y = 14
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 2y = 14 + 4
Combine like terms: -4 + 4 = 0
0 + 2y = 14 + 4
2y = 14 + 4
Combine like terms: 14 + 4 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
The solution to the equation 2y - 4 = 14 is y = 9.
We have,
To solve the equation 2y - 4 = 14, we can isolate the variable y by performing the necessary operations:
First, we add 4 to both sides of the equation to eliminate the -4:
2y - 4 + 4 = 14 + 4
Simplifying, we have:
2y = 18
Next, we divide both sides of the equation by 2 to isolate y:
2y/2 = 18/2
Simplifying further:
y = 9
Therefore,
The solution to the equation 2y - 4 = 14 is y = 9.
